Adult Intussusception at a Tertiary Care Center: A Retrospective Study

Intraoperative Endoscopy in Transient Adult Jejunojejunal Intussusception

Despite improvements in imaging modalities, causative lead points in adult intussusception may be difficult to diagnose. Such lead points can be malignant, causing recurrence or metastases if left unresected. We describe a case of transient adult jejunojejunal intussusception, in which intraoperative endoscopy was used to confirm the absence of a lead point. A 39-year-old woman with a history of laparoscopic oophorectomy presented with epigastric pain, nausea, and vomiting. Contrast computed tomography revealed jejunojejunal intussusception, with no visible lead point. Spontaneous reduction was confirmed during exploratory laparoscopy. After lysis of adhesions, intraoperative peroral jejunoscopy was performed with the surgeons' assistance. Endoscopy confirmed the absence of tumor, and bowel resection was avoided. No recurrence has been observed during 24 months of follow-up. Intraoperative endoscopy may provide additional reassurance for the absence of a lead point in cases where preoperative enteroscopy cannot be performed and no lead points can be identified on imaging.

Heterotopic Gastric Mucosa in the Ileum: A Rare Cause for Intussusception in Adults

Intussusception is the leading cause for intestinal obstruction in children. However, it accounts for only 5% of bowel obstructions in adults. Heterotopic gastric mucosa (HGM) can occur anywhere in the gastrointestinal tract; nevertheless, its occurrence in the small intestine is rare unless associated with remnants of vitelline duct (Meckel's diverticulum). Herein, we describe a case of a 33-year-old male who presented with symptoms and signs of intestinal obstruction caused by ileo-colic intussusception, in which polypoid HGM acted as the organic lead point for intussusception. Several cases of intussusception caused by HGM have been reported in pediatric age group; however, this event is exceedingly rare in adults.
